Historically, we’ve used IR and ultrasonic sensors but [Makers Mashup] decided to use an ESP32-Cam as a motion sensor in his latest animatronic creation.

The Arduino Nano ESP32 based color handheld console by Volos Projects is a fantastic little project that showcases the power and versatility of the Nano ESP32.

Based on an ESP32 (using the Arduino stack) and SDCard for control, and a LiPo cell charged wirelessly, the build is rather tidy.
